I wish I had the same result as the rest of you guys. I went to buy this because all the reviews keep praising this foundation. However I was disappointed with coverage and the formulation. It is very runny, if it was not for the pump I would have had it everywhere. Yes it disappears into my skin but I can pretty much still see what's underneath and I would hate to pile up concealer. It would be good for skin that does not have a lot of blemishes.
I don't have all bad news. I love the fact that it does not transfer at all, and wears all day. Though I have a lil bit of shine.I will try to build it up a bit next time. My colleague said she likes that it gives a neutral look, not too much make-up look.
While I love this product, the crux is that It appeared unnatural on my skin. However, that is my only quibble with it. The nozzle gets a thumbs up because its hygienic. The foundation feels very light, provides medium coverage and really stayed put the whole day. Good for a drugstore brand:)
